GASOLENE LIGHTING SYSTEM.

No. e1 1,823.

Specification of Letters Patent.

Patented Feb. 6, 1906.

Application led August 2, 1902. Renewed July 19, 1905. Serial No. 270,438.

To at whoml t may concern.:

Be it known that I, JOHN B. CHRISTIAN, a citizen of the United States of America, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Gasolene Lighting Systems, of which the following is a specification.

The resent invention relates to that type of gaso ene lightin f system in which the gasolene is piped in a uid condition from a tank outside the building to the series of vaporlamps within the building to be generated into vapor and utilized for lighting purposes in such lamps; and the present improvement has for its object to provide a simple, durablc, and convenient ap aratus for such pur- Eined the features of great safety, a uniform and continuous supply of the gasolene to the series of lamps, an easy and convenient control of the supply of gasolene to the series of lamps in an individual manner, and the prevention of a leakage of any large quantity of gasolene in case of accident to the apparatus by which the gasolene is supplied to the series of lamps, all as will .hereinafter more fully appear and be more particularly pointed out in the claims. I attain such objects by the construction and arrangement of parts illustrated in the accompanymig drawing, which represents in sectlona c ovation a gasolene lighting system embodying the resent improvements.

Referring to the dawing, 1 represents the main storage or supply tank of the s stem,

referably of the gravity form and o a size arge enough to contain an extended supply of gasolene for use in the system.

2 and 3 are twin su ply-tanks superimposed one above the ot er and arranged intermediate of the main tank 1 and the lighting portion of the system. Such tanks are preferably of such size or ca aeity as to hold a suppl oi" gasolene capab e of running the particu ar lighting system for one day or for any other like period of time, as circumstances and the judgment of the constructor may indicate.

The described series of tanks 1, 2, and 3 are arranged outside in an isolated manner, preferably outside the building and within a vault 4 or other like inclosure, the valve mechanism by which the refilling and the feeding of the gasolene from the tanks 2 and 3 is re lated and controlled being extended tlnougil the walls of said inclosure and into the interior of the building for convenient manipulation.

5 is a storac-tank for containing a supply ol compressedg air for use in the system, and 6 a compression-pump of any usual and suitable construction by means of which a supply of compressed air is maintained in said air-storage tank.

is a supply-pipe extending from the lower end of the main tank 1 to the lower end of 'the under tank 2 and provided with a valve 8, by which the flow of gasolene from the tank 1 can be shut off after a iilling of the tank 2 has been effected.

9 is an air-supply pipe extending from the air-storage tank 5 to the top of the under tank 2 and adapted to introduce a supply of compressed air into suoli tank 2.

10 is a valve controlling the supply of air to the tank 2.

11 is a blow-oil' connected to the tank 2, preferably as a branch of the air-supply pipe 9, and provided with a controlling or blowoii valve 12, as shown.

13 is a vertical pipe connecting the tanks 2 and 3 to ether, its lower end extending to near the ottoni of the tank 2, the arrangement being such that with a pressure of air existing in the lower tank the tendency will be to iii-st force the gasolene contained there- "in into the upper tank and then introduce a supply of compressed air into such upper tan 14 is a valve in the pipe controlling the described communication between the tanks 2 and 3.

15 is a gasolene-conducting pipe extending from the bottom of the u per tank 3 to a manifold 16 Within the building and provided with a valve 17 by which the supply of gaso iene Vto such manifold is regulated and con trolled.

18 represents a series of individual conducting pipes or tubes cxtendin in an individual manner from the manifs d 16 to the lamps or burners in the building, and such series of pipes are provided with individual controlling-valves 19 in adjacent relation to the manifold 16, so as to admit of the control of the series of lam s in the buildin from a central point an in an individua manner. In this connection a material part of the present invention consists in the ernplo ent of Wrought-metal tubing of extend ed engths and very small diameter, as the gasolene-conducting tubes or pipes 18 afore- IOC said, in view of the advantages afforded in the present use thereof, as follows: A minimum of gasolene contained within the building in the actual use of the lighting system, in consequence of which the danger therefrom isl correspondingly reduced in case ol' ire or accident, the avoidance of numerous joints, as in ordinary gas-fitting practice, in that each individual tube in the system can be a single piece extending from the manifold 16 to a lamp 20, and ease and eheapness of application in that said tubes can be arranged and applied in manner similar te ordinary electrical wiring in buildings and can be bent, twisted, and entwined to meet any usual and ordinary requirements met with in an application to a building.

20 represents the lamps in the building, which are preferably of the incandescent mantel type now in general use throughout the country.

In the operation of the present apparatus ,l the valve 10, controlling the supply of compressed air to the lower tank 2, is closed, as well as the valve 14, controlling communication between the tanks 2 and 3, while the blow-off valve 12 and the valve 8, controlling communication between the main tank 1 and the lower tank 2, are opened. Under such conditions the gasolene flows by gravity from the main tank 1 into the tank 2, filling the same. The valves S and 12 are then closed, and the valves 10 and 14 opened, and under such conditions a supply of compressed air is introduced into the lower tank 2 to ini tially force the contained gasolenc into the upper tank 3 and subsequently introduce a` burners for any desired period of time in that the mam tank as well as the lower su iply-tank 2, can be refilled asolten as required i without interfering with the constant llow of gasolene from the upper supply-tank i.

llaving thus lolly described my said invention, what 1 claim as new, and desire to secure by [letters Patent, isv

1. ln a gasolene lighting system. of the class herein described, the combination of a main gasolene-storage chamber, an intermediate receiving-ehamber of small capacity connected to the main chamber and adapted to be supplied therefrom by' gravity, means for introducing and controlling a supply ol' compressed air to said intermeiliate chamber, a delivery-chainber of small capacity connected to said intermediate ehan'iber and adapted to be supplied therefrom, means for controlling communication between the chambers aforesaid, a series of stationall, lamps, and pipe (.onneetions between said lamps and the delivery-chamber aforesaid, substantially as set forth.

In a gasolene lighting system of the class herein described, the combination of a main gasolene-storage chamber free from pressure, an intern'iediate receiving-chamber of small capacity connected to the main chamber and adapted to be supplied therefrom by gravity, means for introducing and controlling a supply of compressed air to said intermeiiliate chamber, a delivery-chamber of small capacity connected to said intermediate chamber and adapted to be supplied therefrom, means for ii'laintainiiig pressure in said delivery-chamber, means for controlling communication between the chambers aforesaid, a series of stationary lamps, and pipe connections between said lamps and the delivery-chainber aforesaid, substantially as set forth.
